Question

How do we know the megalodon is extinct if we explored less than 5% of the ocean?

In: 2002

Answer 1

For an animal that large, it’s likely we’d see SOME recent remains of their teeth/carcasses. But the record of them just stopped at a certain point, with nothing recent. Also, the claim that only 5% of the ocean has been explored is a little inaccurate in this context. The ocean has been mapped out and traversed and fished and explored enough that if creatures like megalodon still existed, there almost certainly would have been an encounter.
